BUTTER-MOLD.

SPECIFIGATION forming part of Letters atent No. 740,746, dated October6, 1903. Application led April 27, 1903. Serial No. 154,558. (No modellBe it known that l, "WILLIS SMITH FARNS- WORTH, a citizen of the UnitedStates, residing at Healdsburg, county of Sonoma, State of California,have invented an Improvement in Butter Molds and Cutters; and I herebydeclare the following to be a full, clear, and exact description of thesame.

My invention relates to an apparatus `for molding butter in suitablerectangular masses and after cooling to separate the mass into cubes orrectangularrolls, so called, of required size and Weight. y.

It consists of a base, a box mounted upon said base composed ofseparable sides, with means for locking said sides to the base and toeach other to form a mold within which the mass of butter is shaped, ameans for separating and removing the mold sides after the butter iscooled without mutilating the 'mass, and cutter guides with means forattaching them to the base, so that the butter maybe separated into thedesired forms.

It also comprises removable bottom sections fitting the base andseparable upon the lines of the cuts made in the butter, and receiversupon which the butter may be transferred from said bottoms withouthandling.

My invention also comprises details of coni struction which will be morefully explained by reference to the accompanying drawings, in whichFigure l is a partial sectional elevation of the mold. Fig. 2 is asimilar view at right angles with Fig. l. Fig. 3 is a perspective viewshowing the mold sides removed and the cutter-guides in position. Fig.4: shows a roll of butter upon a receiver. Fig. 5 is a view of thecutter.

It is the object of my invention to provide a convenient mold in which amass of butter may be packed and shaped to a form which will containany' multiples of the rectangular rolls,. (as they are called,)which-form the unit of measurement, as one pound, one and one-halfpounds, or two pounds, to provide a means for securely interlocking thelsides of thi'smold and securing them-to the base, means by which theymay be readily disengaged and removed from the butter without slidingthereon, so as to` mutilate the mass, supplemental devices attachable tothe 'base forming guides for a cutter by which the mass may beaccurately divided into the units or packages in which the butter iseventually marketed, and means for removing` these packages to be packedwithout any contact of the hands.

A is a base, made of wood. or suitable material, preferably having anopen center and surrounding rails or ledges' 2, which form a borderwithin which the sides 3 and ends 4 are set. The length of the sides andends is determined by the amount of butter which it is desirable to moldat each operation.

These molds may be of any size capable of holding from two to thirty ofthe Arectangular rolls or packages into which they butter is eventuallyseparated, and they may have a depth such as to form rolls of anydesired weight. These packages are, strictly'spea-king, rectangularA.packages having various length and diameter. The technical name forthese packages is rollsf andin hereinafter describing the packages Ishall employ this designation for them.

It will be understood that the bottom of the apparatus, if small, mightbe made entire and without central openings; but for the larger sizes itis lighter and more convenient to make it with a central opening and aledge a, projecting inwardly within the raised ledges 2 to serve asasupport for the sides and ends of the mold and also to receive thetransverse bars 5. These bars are preferably made, as shown, ofsuperposed layers or strips which may be secured togetherland the barsthemselves secured by screws or otherwise upon the ledges a, extendingacross the open center of the mold. The bottom boards 6 of the i moldare supported upon these transverse bars and are of such a length andtotal width as vto leave a-suilicient vertical space between themselvesand the ledges 2 to receive the side and end sections of the mold,which' iit closely. The length of the bottom boards maybe equal to themultiple 'of the number of rolls into which the mass is to bevcut. Thusin the present case I have shown the mold as being of a size to formsixteen rolls and each of these bottom boards will therefore 'beef a 4length to support four rolls standing on end. ,Thedivision-lines"between these bottom ICO boards are such that each boardis just equal' i to the transverse width of the rolls which aresupported upon it, so that when the mass of butter has been formed andsubdivided and the sides of the mold removed these bottom boards can beeach lifted separately with the roll standing on end upon it, and thebutter may be transferred upon the receivers 7 by simply tilting thebottom boards in line with a series of four of these receivers, whichhave handles, as shown, so that the separate rolls can be transferredwithout ever being touched by the hands.

In order to secure the sides and ends of the mold to the base, I haveshown two opposite sections of the ledge 2 as formed withinwardly-projecting flanges or extensions, as shown at 2, These may beformed upon either the sides or the ends, depending upon the shape ofthe mold.

If the mold be exactly square, as in the present case, it will beunderstood that the projections 2 may be made upon either of v theopposing bars which form the ledge. I

prefer, however, to make them upon the ones which form the ends of .themold, and the bottoms of these ends are correspondingly grooved, as at8, so that by tilting them when they are introduced into the spacebetween the ledges 2 and the bottom boards 6 these grooves would be madeto engage the projections 2a, and thus interlock the ends firmly withthe base, While the inner faces of the sides and ends iit against theedges of the bottoms 6. At a suitable point intermediate between thebottom and the top of the sides 4 are projecting tenons 9, and these areso formed as to slip through mortises lO, made in the end boards, sothat when the side boards are set in and brought into a verticalposition the tenons or dowels 9 will pass through the mortises 10 andproject a little outside. In order to insure a snug fit and a unitarystructure when the sides and ends are secured together, the ends arechanneled, as shown at 11, so that the vertical edges of the sides 3 fitinto these channels. The portions of the tenons 9 which project outsidebeyond the outer faces of the sides 3 have grooves or channels 12 cutvertically in them, and these are engaged by swinging bars 13, which arecentrally pivoted, and the ends will engage with the grooves 12,and thussecurelylock the sides and ends together. The grooves 12 preferably haveone side inclined, and the ends of the bars 13 are made wedge-shaped orinclined in the direction of their movementwhen engaging the grooves 12.The object of this is to draw the sides firmly against the abutting endsand form close joints at the angles of the mold. The mold being thuscompleted, there is no danger of the parts being separated from eachother or from the base. It may then be filled with the butter-and packedsolid, the top being leveled oif by a striker in any usual or suitablemanner. The butter being comparatively soft when first packed into theboxes, it is desirable to allow it to become hard, and it is thereforeleft in the mold until this result takes place either by artificial ornatural cooling. The sides are then disengaged from the ends by firstturning the lock*- ing-bars 13 and disengaging them from the tongues 9.The ends may then be tilted outwardly and disengaged from thelockingflanges 2 and then lifted clear of the. butter and removedwithout further contact. The sides are similarly tilted, and the butterthen remains standing on the base-board 6. The next portion of theoperation consists in cutting the butter into the rectangular rolls inwhich it is to be packed for the market. The size of these rolls to makea certain Weight for a certain length having been determined, it will beeasy to make all the rolls within the mold of substantially the sameweight by building up the transversebars 5, so that the depth from thebottom 6 to the top taken with the transverse diameters of the rollswill make a certain weight. I then iit guides or standards into thespaces in the surrounding ledge a exterior to the bottom boards 6. Theseguides are preferably in the form of vertical bars or standards 14,having vertical slits 15 made in them. These standards 14 are tted intoa base or bases 16 either by mortising, doweling, or otherwise.

I have here shown a number of standards corresponding with the number ofdivisions which are to be made in the mass which has been formed withinthe mold, divided as hereinbefore described. Such a mass being capableof forming sixteen rolls, I have shown three of the standards 14 fixedto a single base 16. This base is provided with pins or equivalentlocking devices, as at 17, and these pins fit into corresponding holesmade in the ledge a of the base. A set of these standards having Vbeenplaced, for instance, at each end of the mass of butter after the moldhas been removed, a suitable cutter is introduced into the slots 15 atopposite ends and sawed down to the bottom, thus separating the mass.The channels 15 in the standards 14 serve as guides to give the cutterthe proper direction and insure a straight cut, and by reason of theseguiding channels or slots having the two sides the cutter will beremoved in the same line that it made its cut. There is no danger ofslicing off a small piece on the return, as would be the case when thereis only one side to the guide. When all the cuts have been made in onedirection,the standards 14 are removed and replaced on the sides of theledge a and the cutters again used to subdivide the pieces into theproper-sized rectangular rolls. The cutter may be of any suitabledescription. I have here shown it as made of Wire 18, stretched tightlybetween the ends of a frame Which is preferably formed of elastic steel,so as to maintain the proper tension on the cuttingwire. When the butterhas thus been subdivided, it is onlynecessaryto lift the bottom boards 6successively, and the receivers '7,

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination in a butter-mold of a base having upturned ledgeswith horizontal interiorly-projecting' anges upon two opposite ledges,sides and ends adapted to inter-l lock at their meeting edges and two ofsaid sides having grooves or channels corresponding with the iiangeswhereby' they are secured to the base.

2. The combination in a butter-mold of a base having upwardly-projectingsurrounding ledges and horizontal flanges projecting inwardly from twoopposite sides, mold sides adapted to stand wit-hin said ledges andtransverse grooves or channels formed in two of said sides adapted toengage the iianges of the ledges, interlocking tenons and mortisesformed in the meeting edges of the sides and means for securingthetenons in the mortises.

3. The combination in a butter-mold of a base, vertical separable sides,means includ- Ywith which slots the ends of the bars are adapted tointerlock.

4. The combination in a butter-mold of a base, independent separa blesides and means including ledges on the base and a iiange-and-- grooveconnection between the ledges and the sides for locking sides to thebase, two of said sides having mortises and coincident vertical channelsformed near their ends, tenons formed on the other sides adapted to passthrough the mortises, said tenons having vertically tapered or inclinedchannels made exterior to the sides through which they pass, barscentrally pivoted and turnable to engage said channels, said bars havingthe ends beveled or inclined to interlock with the channels and draw thesides of the mold rmly together.

5. The combination in a butter-mold of a base, independent sides withmeans for lock# ing them to the base and to each other, a bottom andsupports therefor, said bottom being formed of superposed sections tovary the length of the rolls and subdivided' longitudinally into widthsequal to the transverse width of each of the rolls when separated.

6. The combination in a butter molding and cutting apparatus of a base,sides adapted to be interlocked with the base and with each other toform a preliminary mold, vermovable sections equal in width to thetrans- 'i verse width of the rolls whereby each set of rolls may belifted and transferred to independent receivers. y

In witness whereof I have hereunto set my hand.
